Hybrid tea rose plant named Hilcot

ABSTRACT

A new variety of hybrid tea rose having peach flowers produced on a plant suitable for greenhouse growing.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class, which was originated by my crossing as the seed parent the variety meirilocra known as `Capella`, U.S. Plant Pat. No. 4,868, and as the pollen parent the variety known as `Golden Fantasie`, U.S. Plant Pat. No. 3,272. The varietal denomination of this new rose is `Hilcot`.

Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware are its attractive flowers having unusual opening coloration. At the cut flower stage the blooms appear as an orange blend. However, suggestions of peach tones appear when the bloom is about one-half open. At the open bloom stage the color tends to be seen as a yellow blend. The flowers are large and are borne singly in a manner typical of hybrid tea varieties and the plant produces strong, upright canes with rich, green foliage.

Asexual reproduction by propagation by grafting of the new variety as performed in Richmond, Ind. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. The new variety can be asexually propagated by budding, grafting, propagation from cuttings and micropropagation.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustrations show typical specimens of the flowers and vegetative growth of the new variety depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character. Phenotypic expression, including colors, may vary depending upon growing conditions, such as climate, soil, and cultivation conditions.

One of the accompanying illustrations shows plant parts, including compound three and five leaflets leans, a stem, new growth, buds after sepals part and after sepals fall, a bloom 1/3 open and a bloom fully open. The other illustration depicts typical form and configuration of flower and bud as cut flowers.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color descriptions herein refers to plate numbers in the aforementioned color chart.

Parentage: Seedling

Seed parent.--Meirilocra (also known as Capella).
